Pain is the most common symptom of sinusitis. You have several different sinuses above and below your eyes as well as behind your nose. Any of these can hurt when you have a sinus infection. Inflammation and swelling cause your sinuses to ache with a dull pressure. You may feel pain in your forehead, on either side of your nose, in your upper jaws and teeth, or between your eyes. This may lead to a headache (see below).
The symptoms of acute sinusitis in adults usually follow a cold that does not get better or gets worse after 5 - 7 days. Symptoms include: 1  Bad breath or loss of smell. 2  Cough, often worse at night. 3  Fatigue and general feeling of being ill. 4  Fever. 5  Headache -- pressure-like pain, pain behind the eyes, toothache, or tenderness of the face. 6  Nasal stuffiness and discharge.
